what is the craziest thing you've done that made you feel life?

I am at my craziest when I'm around people who permits me to act insane. Whenever they're there I don't really mind anything else at all, because I know that they're going bail me out of jail or out of a mental institute to attest that I'm normal. ;)
But really, the craziest that I've done I guess was when I was randomly calling out my closest friend's crush across the mall, with hopes that we'll find him. My friend was just beside me, laughing his heart out. It was really interesting.
Well there are other crazy things, and it's just one of those that I've really enjoyed. I felt so free and careless, but I felt like at that particular time, it was okay.
Have you had moments like these? :)
